GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent N 0. 672,596, dated April23, 1901. i Application filed January 19, 190].- Serial No. 43,897. (Nomodel.)

To all whom it may concern:

Be it known that we, GAYLARD W. DENYES and OWEN SOHUTT, citizens oftheUnited States, residing at Gassopolis, in the county of Cass and Stateof Michigan, have invented certain new and useful Improvements inGrain-Drills; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Onrinvention relates to improvements in grain-drills, and moreparticularly to that class of drills in which a shoe is yieldinglypressed into the soil by means of a spring; and its objects are toprovide improved means for adjusting the tension on the spring, toprovide improved means for securing the spring in place, to provide asimple and durable device, and to provide the device with certain newand useful features hereinafter more fully described, and particularlypointed out in the claims, reference being had to the accompanyingdrawings, in which- Figure 1 is a plan view of a device embodying ourinvention. Fig.2 is a side elevation of the same with parts broken away;Fig. 3, a detail of the adjusting-cam; Fig. 4, a detail of thecam-holding plate; Fig. 5, a detail of the fulcrum-block; Fig. 6,adetail section of the T-head before attachment to the spring, and Fig.7 the same after attachment to the spring.

Like letters refer to like parts in all the figures.

A represents a portion of the frame of the drill; B, one of thedrill-shoes; G, the drawbars for the shoe, extending forward and upwardin a curve from the front of the shoe and pivoted at the forward end tothe frame.

D is a tube extending vertically from the rear of the shoe to conductthe grain to the shoe.

D represents lugs extending laterally from the upper part of the tube D,which lugs are engaged by the parallel bars E to lift the shoe clear ofthe soil when the machine is out of action. The bars E extendhorizontally at each side of the tube D, and thence vertically at therear of the tube and are pivoted to the vertically-movable end of therocker-arm F, attached to a rook-shaft G, which shaft is adjusted bymeans of a lever H, having a latch to engage a notched sector I, fixedon the frame.

Pivoted in the forward endsof the bars E is a T-head P, having atransverse opening, in which is inserted the end of the spring J. Tosecure this spring in the T-head, lugs P P are provided at each side ofthe opening in the head, and these lugs are bent inward and engaged withrecesses in the opposite sides of the spring, as illustrated in Figs. 6and 7. The spring J extends forward to between the draw-bars 0, near theforward part of the same, and is there bent downward and rearward in acurve and engages a fulcrum-block K, secured between the draw-bars byatbolt L and having flanges N engaging the drawhars to aid in holdingthe block in place. The fulcrum-block K is also provided with a loop K,engaging and holding the spring-arm J from moving forward. Thespring-arm Jextends rearward between the draw-bars G and engages theupper side of a grooved eccentric M, rotatively adjustable betweenplates 0 O,

engaging the respective draw-bars.

One of the plates 0 is provided with a corrugated boss 0, which engagesand meshes with like corrugations in the end M of the hub of theeccentric. The other end M of this hub is made hexagon or square toreceive a wrench by which the eccentric may be turned to adjust the sameand put tension on the spring-arm J. A bolt L passes through thedraw-bars, plates, and eccentric and secures the whole firmly in place.

From the foregoing description the operation of our device will bereadily understood without further description.

What we claim, and desire to secure by Letters Patent, is-

l. The combination of a shoe, draw-bars attached to the shoe and pivotedto the frame, a fulcru m-block and an adjustable eccentric attached tothe draw bars, a spring engaging the fulcrum-block and eccentric, andmeans for adjusting the tension of the spring, substantially asdescribed.

2. The combination of a shoe, draw-bars attached to the shoe and pivotedto the frame, a fulcrum-block between the draw-bars, an eccentricbetween the bars and rotatively adj ustable, a spring engaging theeccentric near one end and having a bent portion engaging thefulcrum-block, and a vertically-adjustable arm connected to the otherend of the spring, substantially as described.

bars, an eccentric between the bars having a hub provided withcorrugations in the end and a squared portion, a plate attached to oneof the draw-bars and having a corrugated boss engaging the corrugatedend of the hub, a bolt passing through the draw-bars, plate, and hub, aspring engaging the fulcrum-block andeccentric at the forward end, andmeans for vertically adjusting the rear end of the spring, substantiallyas described.

5. The combination of a shoe, draw-bars attached to the shoe at the rearand pivoted at the front, a fulcrum-block having flanges to engage thedraw-bars and a loop to engage the spring, a bolt extending through thedrawbars and block, an eccentric having a hub provided with a squaredportion and end corrugations, plates engaging the ends of the hubs andprovided with corrugations engaging the corrugations in the hub, a boltextending through the bars, the plates, and the hub, a spring engagingthe fulcrum-block and the eccentric at one end, and means for verticallyadjusting the other end of the spring, substantially as described.

6. The described means of securing a T- head-to a spring, consisting ofan opening in the T- head to receive the spring, a recess in the springand a lug on the head adapted to be bent and engage with the recess inthe spring, substantially as described.

7. In a grain-drill, in combination with a spring attached to thedraw-bars of a shoe and provided with opposing recesses, and parallelbars attached to a vertically-adjustable arm, a T-head pivoted in thebars and having'an opening to receive a spring, and lugs at each side ofthe opening to engage the recesses in the spring, substantially asdescribed.

8. In a grain-drill, the combination of a shoe, a tube on the shoe,laterally-projecting lugs on the tube, draw-bars attached to the shoeatthe rear end and pivoted at the front end, a fulcrum-block and anadjustable eccentric between the draw-bar's, a vertically adjustablearm, parallel bars pivoted to the arm and embracing the tube, a springengaging the fulcrum-block and eccentric, and a T- head pivoted in theparallel bars and attached to the spring, substantially as described.

In testimony whereof we affix our signatures in presence of twoWitnesses.
